How do you determine the order of reactivity series?
Mademuasel [1]

The order of reactivity series is Most reactive metals are at the top while the least reactive metals are at the bottom.

A reaction series is a list of metals arranged in descending order of reactivity. The most reactive metals are on top and the least reactive metals are on the bottom. If there are any two metals in the column, the metal placed at the top of the column can displace the bottom metal from the brine.

The more reactive the metal the faster the reaction. Metals below hydrogen in the reaction sequence do not react with dilute acids. Platinum is placed below gold in the reaction sequence. The elements in the lower left corner of the periodic table are the most active metals in the sense that they are the most reactive.

4. Electrical energy is often transformed from the ___?_____ energy of falling water.
Charra [1.4K]

Answer:

4: Hydro electrical energy

5:Flase the law of conservation of energy is not violated by transformer.

Explanation:

4:Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.

5:Quantum Physics and Law of Conservation of Energy.

Niels Bohr, Hans Kramers, and John Slater proposed that these electrons violated the law of conservation of Energy momentarily. They stated that with each jump, energy is either created or destroyed by the electrons during the whole process.

QUE VENTAJAS TIENE PARA LA PLANTA Y EL CULTIVO LA PERMANENCIA DEL POTASIO COMO CATION MONOVALENTE (K+)?
yarga [219]

Explanation:

Son muchos los beneficios del catión monovalente (K+) en las plantas y cultivos, mencionaremos algunos:

-Interviene en el proceso de apertura y cierre de los estomas; el catión (k+) ayuda a que los estomas puedan realizar correctamente  el proceso de la fotosíntesis es decir  la absorción del dióxido de carbono para producir oxígeno y agua; este proceso ayuda a que la planta pueda fabricar su propio alimento es decir transformar materiales inorgánicos en orgánicos como azúcares y carbohidratos que son aprovechables por la planta para realizar diversas funciones catalíticas como la respiración celular,la fosforilación y la síntesis de proteínas; este proceso también contribuye a que la planta pueda almacenar y retener suficiente agua lo cual ayuda a evitar el estrés hídrico en la planta.

Por lo tanto si la planta tiene una buena concentración de potasio como catión monovalente(k+); es posible que tenga un buen crecimiento y desarrollo radicular ,así mismo la calidad de los cultivos será muy buena,seran cultivos muy nutritivos y saludables. Algunos cultivos que necesitan una alta cantidad de potasio son los cítricos y el banano.
